(1) The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced
accuracy requirements.
(2) The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be appliedwith reduced
accuracy requirements.
(3) The accuracy limitsminimum external differential reference voltage. Lower differential reference voltage levels may be appliedwith
reduced accuracy requirements.
